Title: Central heating system programmer and controller - has time switch with heating element close to thermostat
IPC: G05D23/32
Filed: 1974-09-24
Abstract: The programmer consists of an electric resistance heating element and a time switch which controls the current to the heating element. The element is placed near the central heating system room thermostat and its heating effect alters the local temperature by several degrees so that the thermostat switches the heating off at a lower room temperature than that at which it is set. The programmer is entirely separate from the heating system and can be installed separately from it. The occupier can vary the setting of the time switch and can control the influence of the programmer on the heating by positioning the heating element nearer to or further away from the room thermostat.

Title: Gas turbine/nuclear power installation - in which waste heat is taken from cooling water, vaporised and fed to condensation turbines
IPC: F01K21/00
Filed: 1975-06-18
Abstract: In an enclosed gas turbine-nuclear power installation with a steam power installation connected behind it, the exhaust heat of the gas turbine process is used in a waste heat follow-on process for steam and current prodn. The exhaust heat from the gas turbine process is taken from the cooling water, whereby the water-side pressure in the cooler is such that it is higher than the gas-side pressure, and no vaporisation of the cooling water occurs inside the cooler. The cooling water under pressure is fed out through one or more expansion stages divided into steam and condensation phases, and the steam produced through expansion is fed away to motivate one or more condensation turbines.

Title: Thermoplastic film charged with monocalcic glass microspheres - to prevent the turns sticking together when the film is rolled up
Inventor: GIRARD VINCENT
IPC: C08J5/18
Filed: 1975-12-09
Abstract: Adjacent turns in rolls of thermoplastic film are prevented from sticking together by adding monocalcic glass microspheres to the plastic.
